MM54HC4511/MM74HC4511
BCD-to-7 Segment Latch/Decoder/Driver
General Description
This high speed latch/decoder/driver utilizes advanced sili-
con-gate CMOS technology. It has the high noise immunity
and low power consumption of standard CMOS integrated
circuits, as well as the ability to drive 10 LS-TTL loads. The
circuit provides the functions of a 4-bit storage latch, an
8421 BCD-to-seven segment decoder, and an output drive
capability. Lamp test (LT), blanking (Bl), and latch enable
(LE) inputs are used to test the display, to turn-off or pulse
modulate the brightness of the display, and to store a BCD
code, respectively. It can be used with seven-segment light
emitting diodes (LED), incandescent, fluorescent, gas dis-
charge, or liquid crystal readouts either directly or indirectly.
Applications include instrument (e.g., counter, DVM, etc.)
display driver, computer/calculator display driver, cockpit
display driver, and various clock, watch, and timer uses.
The 54HC/74HC logic family is speed, function, and pinout
compatible with the standard 54LS/74LS logic family. All
inputs are protected from damage due to static discharge by
internal diode clamps to V
CC
and ground.
